The first municipal utility Denison formed was their water utility. In November of 1884, the people of Denison created their first water system. While the system was simple in those days, it has evolved until today; it is capable of serving Denison and part of the rural areas and communities near Denison. The current facility can produce seven million gallons of water each day. Here are the policies and procedures we utilize to get this important job doneService CharacteristicsThe Utility will make available, throughout its service area, water service of a character determined by the Utility to meet the needs of the customers.In supplying this service, the utility shall own and maintain all facilities up to and including the corporation valve and saddle attached to the main. The utility, in addition, owns and maintains the water meter and meter set. The property owner shall own and maintain, the water service line from the curb stop to the building. All valves, riser boxes and other equipment attached to the service line are the responsibility of the Utility.Service ExtensionsWater main extensions into new developments are installed by the developer according to utility standards, and then deeded to the City of Denison - Municipal Utilities. These rules and procedures are spelled out in the Planning and Zoning Ordinances of the City of Denison, and administered by the Building Inspector of the City of Denison.The utility, at its expense, maintains, replaces and enhances the water mains that are part of the system.Main extensions will be constructed along existing public roads, streets and alleys, wherever practicable.It is the policy of the DMU to furnish water at retail both inside Denison as well as certain areas outside Denison. When a municipal water main is extended outside Denison it shall be authorized by action of the Utility Board of Trustees.

First, a 500,000-gallon and a 1.5 MG. clear well are located at the water treatment plant. These units are used as a reservoir for high service pump suction and to permit flexibility of operation at the water treatment plantThe other three (3) storage facilities are elevated tanks within the system. A one million gallon elevated tank near the high school and a 500,000 gallon tank located on 16th Street at 4th Avenue North serve the majority of the community and receive flow and pressure from high service pumps at the water treatment plant. A 200,000-gallon tank located north of 6th Avenue North near the ball fields and a portion of the distribution system it serves are isolated from the remainder of the system by a booster pump station on 6th Avenue North.Water mains and fire hydrants are replaced and upgraded as the needs meritsWater Supply WellsAll water for the community is obtained from eleven (11) wells. Six are in the South well field in and around Denison, five are in the North well field, 2 miles north of Denison on Hwy. 39Water Treatment PlantThe Denison water treatment plant was constructed in 1962. It was modified slightly in 1985. In 2001, a major plant reconstruction was completed that enlarged the plant's maximum capacity to 7.0 million gallons per day. The plant serves all of Denison retail water needs. It also supplies water under a wholesale contract with West Central Iowa Rural Water Association of Manning, Iowa.After filtration, the water is fluoridated and chlorinated prior to its being pumped to the distribution system.Chemicals used in the water treatment plant include lime, sodium aluminate, carbon dioxide, chlorine, and fluoride. Carbon dioxide gas is delivered in bulk form and stored in a refrigeration unit. Fluoride is delivered in drums and is fed as a liquid.Solid materials removed from the water treatment plant are stored in lagoons located south and west of the plant. Periodically, these lagoons are cleaned by private contractors. Backwash water used to clean the filters is stored in a recovery basin. This water is recycled back to the head of the plant for re-treatment and reuse. The solids in the backwash water are removed in the upflow clarifier and also disposed of in the lagoon. The backwash recovery basin was constructed in 1973.Denison's Water Treatment Plant is a Grade III plant, and as such, a grade III certified operator shall have direct responsible charge. The treatment plant shall be run by certified operators, complying with the provisions of the state permitService Rules (Tariff)Some of the service rules of the Denison Municipal Electric Utility are regulated by the Iowa Utility Board, (IUB).
